Is Kvass Only Made with Beets?
If you’re a long-time viewer, you have probably seen my video where I showed you how to make Beet Kvass. This tasty probiotic-rich drink is made with fresh beets.
Traditional kvass, which originated in Russia and Eastern Europe, is usually made with stale rye bread instead of beets. Were beets added sometimes? Sure. But to be truly authentic, it’s worth making this probiotic-rich drink with rye bread for a beverage that is both sweet, tangy, and effervescent!
Is There Just One Kvass Recipe?
Kvass has been made for thousands of years, and truth be told, there is probably no one “official” recipe. Each country, each region, and even each family probably have their own way of making this unique drink.
I have been experimenting with a Kvass recipe for about two years, and I have discovered a combination that I like. My printable recipe is a simple one. All you need is some stale dark rye bread, a generous handful of raisins, and two apples. That’s it! And of course, some water to top it all off. I show you how to mix all the ingredients together in my recipe video.
Get Started Making Kvass Today
Since you may want a long ferment time, get started making your Kvass today. Your recipe may be ready in 2 days, but you may also want to allow it to ferment—in essence, to “brew”—for a total of 30 days. Each stage in the brewing process creates a slightly different flavored beverage.
Within the first few days, your Kvass will be slightly sweet. After about a week or two, it will be quite effervescent with more of a yeasty flavor that’s similar to Kombucha. And after 30 days…well, all I can say is if you brew it that long it will put hair on your chest! LOL!! After a month of fermentation, it takes on a powerful—almost vinegar-like flavor—similar to Fire Cider.
More Probiotic-Rich Drinks
Now that you have learned how to make real Kvass, try making other probiotic-rich drinks by watching the following videos and recipes.

Traditional Rye Bread Kvass

Equipment
- 64-ounce glass jar with screw-on lid
- Swing top bottles (for decanting), optional
Ingredients
- 5 slices Stale or toasted dark rye bread, broken into pieces
- 1/2 cup Dark raisins
- 2 large Apples, unpeeled and chopped into pieces, seeds removed
- Water, preferably chlorine-free
Instructions
- Add all dry ingredients into the jar and shake to mix well. (See video.)
- Fill the jar with water leaving approximately 2 inches of headspace from the rim of the jar.
- Put a lid on the jar and screw it on tight. Shake the jar vigorously.
- Place the jar in a bowl (to catch any spillage), and place it in a warm (room temperature is fine) spot in the kitchen or pantry out of direct sunlight.
- Each day, loosen the lid to allow any built-up carbon dioxide gas to escape.
- Retighten the lid securely and shake the jar. Place the jar back into the bowl, and return the bowl to a warm spot in the kitchen or pantry out of direct sunlight.
- After two days, begin to taste the kvass. You can let the kvass ferment up to 30 days. Once it reaches a flavor that you like, strain out the solids, and decant the liquid into a bottle and refrigerate.
- Kvass will stay fresh in your refrigerator for at least six months. It will lose its "fizz" after a few days unless decanted into a swing-top bottle. Take caution if you decide to decant your kvass into a swing-top bottle. Make sure the bottles are specifically made for decanting effervescent beverages. Even under the best conditions, naturally fermented beverages can cause swing-top bottles to break. I do not recommend using them.
